US 2022/0066574 A1 · DATA FILTERING DEVICE AND DATA FILTERING METHOD

Abstract

A data filtering device stores a piece of standard track data and a piece of target track data. The piece of standard track data corresponds to a standard track in a six degree-of-freedom (DoF) virtual space constructed by a plurality of virtual space units, and the piece of target track data corresponds to a target track in the six-DoF space. The data filtering device determines whether a degree of similarity between the standard track and the target track is lower than a threshold of similarity. When determining that the degree of similarity is lower than the threshold of similarity, the data filtering device classifies the piece of target track data as an invalid data.

Dependent claims

A data filtering device, comprising:

a storage, configured to store a piece of standard track data and a piece of target track data, the piece of standard track data corresponding to a standard track in a six-degrees-of-freedom (DoF) virtual space constructed by a plurality of virtual space units, the piece of target track data corresponding to a target track in the six-DoF virtual space;
and
a processor electrically connected to the storage, being configured to:
determine whether a degree of similarity between the standard track and the target track is lower than a threshold of similarity;
and
classify the piece of target track data as a piece of invalid data which will not be used in a process of machine learning of a track recognition model when determining that the degree of similarity is lower than the threshold of similarity.
